(2) i10D4 - Incriminator Audio 10" 500W RMS Dual 4-Ohm Subwoofers Features & Specifications: The I Series Subwoofers from Incriminator Audio were designed with the entry level consumer in mind. Rated at a very conservative 500 watts RMS, the large voice coil and magnet structure of this line of drivers give entry level a new meaning. Other entry level subwoofers are designed with cosmetics in mind, hoping to prey on inexperienced users, but not the I Series. It was designed strictly with performance and functionality in mind. The consumers money isn’t wasted on flashy parts and useless lighting. Instead the I Series owner is getting a reliable, strong, solid subwoofer that is very loud and produces clean sounding tight bass that one would expect to hear from a much higher priced line of subwoofers. The I Series line of subwoofers is offered in 10”, and 12” models and all have the option of dual 2 or dual 4 ohm voice coils.
